The daughter of a murdered Jewish businessman has spoken out for the first time about finding her father dead.

John Luper, who was 57, died following a robbery at his home on February 17, 2004.

Police believe he was attacked by a group of up to five masked men as he walked his dog before being dragged back to his Sandmoor Drive property in Alwoodley, Leeds.

His wife, daughter and au pair were tied up by the robbers, who fled with £100,000 worth of cash and jewellery.

Mr Luper was found dead from asphyxiation. His attackers have never been found.

His daughter Liza-Rose, now 32, revealed the family’s anguish on the 12th anniversary of his death.

She told the Yorkshire Evening Post: “I just remember waking up to being tied up by masked men and when I was finally free finding my father dead on the floor.

“It has been 12 years and a lot has happened but there are a few people out there who have some information about who killed my dad. I just want justice.”

She added a plea for any information: “The message I would say is please help me.

“Everybody has a father and a father is a daughter’s first love so I literally feel like my heart has been torn out, broken and crushed.

“Please help me find the murderers.”

Mr Luper was an active member of the local United Hebrew Congregation, where the Luper Room is used for receptions and board meetings. He also supported UJIA.

The family once ran the country’s biggest suit factory, servicing high street names such as Burton and Burberry.
